This invention relates to devices for supporting wires, conduits and like lines in shipbuilding where such lines are passed through openings in bulkheads and it is desirable to secure such lines against movement relative to the bulkhead as well as to afford an added support therefor at the bulkhead, so 3 that derangement, chafing, wear and damage of the lines are prevented.

An object of my invention is to provide a device of the character described which is of simple and inexpensive one-piece" construction subject to being readily and easily mounted in the bulkhead opening through which the line is to be extended and secured to the bulkhead without the use of extraneous fastenings and in a much more expeditious manner than heretofore.

Another object is to provide a clip or support of the character described which is ilxed to the bulkhead so that thereafter the line may be extended through the clip and bulkhead and the clip then clamped on the line in an efllcacious manner by reason of the construction of the particular one-piece formation and the integral and bendable fastening tongues thereon.

Another object of my invention is to provide a bulkhead clip of the character described which may be readily stampedirom a blank of sheet metal as a one-piece unit requiring only the addition of a nut and bolt to clamp the device to the conduit or other line. I

With the foregoing objects in view, together with such other objects and subsequently appear, the invention resides in the partsand in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a side elevation of a clip embodying the present invention;

Fig. 2 is an end elevation of the clip;

Fig. 3 is a side elevation of the clip asinstalled in a bulkhead to support and secure a conduit;

Fig. 4 is an end showing the conduit in cross section;

Fig. 5 is a fragmentary top plan view of the clip as installed.

As shown in the iaccompanying drawing, one embodiment of the clip of the present invention is made in one piece from suitable resilient sheet I in the form of an elongated and longitudinally split sleeve l adapted to embrace a conduit or line 2 and to be secured in the opening 3 of the bulkhead 4, through which opening the conduit or line is extended.

Adjacent one end 01 the sleeve i are outwardly extended opposed apertured ears or lugs 5 formed integral with the sleeve at the opposed edges or the split and adapted to be drawn together by advantages as may 7 Claims. (Cl. 248-56) means of a bolt 6 and nut I to clamp the sleeve on the conduit.

At the other end of the sleeve I, rectangular recesses or cut-outs 8 are made to define a plurality of bendable tongues 0 which normally extend axially and as continuation portions of the sleeve. 1

Between the inner ends of the tongues 9 and the ears 5 are rectangular openings in which extend circumierentially of the sleeve to lighten it and also provide material for forming radially extending stop lugs I l adapted to engage one side 01' the bulkhead as shown in Figs. 3 and 4. When the sleeve is inserted through the bulkhead opening 3 and the lugs ll abut the bulkhead to limit ends engage the bulkhead, which causes them to perform their spring action with maximum efllciency. l

The sleeve I may be first inserted and then aflixed in the bulkhead'opening 3 after which the conduit is extended therethrough and the,

bolt 6 tightened to clamp the outer end portion of the sleeve on the conduit. As a conduit or line is usually covered with rubber or yleldable or compressible material, the clamped end of the sleeve, due to its length and the longitudinal split,

will be constricted to a greater extent than the end in the opening 3. This causes the sleeve to elevation 01' the installed clip looking in the direction of the arrow in Fig. 3 and take a conical form somewhat as shown by slight exaggeration in Fig.5, with the larger or base end of the cone snusl-Yiltted in the opening 3. With the clip thus installed the conduit is held securely against longitudinal movement relative to the bulkhead and eflectively supported on a wide and long wear preventing seat aiiorded by the sleeve l.

The clip serves as an eifective anchoring and supporting means for a conduit line or wires and positively prevents movement of the line relative o the bulkhead.

, The stop lugs it provide for a quick application of the clip to the bulkhead and insure the proper positioning thereof in the opening 3 tolikewise permit of a ready bending of the tongues a into the holding position shown in Fig. 3.

Another feature of importance assuring a comparatively snug fit oi the clip in the bulkhead opening and a reliable holding of the conduit line or wires in the desired position, is the provision for constricting .the outer portion of the sleeve which carries the clamping ears 5 so that it has a smaller diameter than the pc on of the sleeve resting in the bulkhead opening, this being made possible by the resiliency oi the sleeve. its elongation and the longitudinal split thereof, whether the conduit is rigid or yieldably compressible.

As here shown the sleeve I may be provided on its longitudinal median line with a rib l2 which aids in holding the cable, conduit line or wires .against longitudinalmovement relative to the sleeve, as said rib will bite into the cable or other line and therefore securely grip and hold the line when the sleeve is clamped thereon.

While I have shown and described a specific embodiment of my invention I do not limit myseli to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.

I claim:
